Noticed in my last game as PAC once a tech that offered a wonder was researched and had become available it offered the one turn construction perk. Problem was it also offered everything in my cities queue in one turn as well. Not sure if it also affected units in hindsight but it did make buildings all one turn.
I went ahead and spit out a warp spire building with it in a single turn and afterwards the available wonder had gone back to normal cost along with everything else.
Then once I unlocked another wonder the same city was presented the same opportunity since it had not built a wonder.

Can not reproduce the bug. Tried to test it further in a new game today and the perk seemed to be working as intended. Could have something to do with unlocking an artifact wonder; perhaps unlocking artifact wonder before a tech tree wonder? Wanted to see if it would affect all available cities but can't figure out what triggered it to begin with. Will keep an eye out for it in the future and try to identify what causes it if I happen to see it again.
